Human Recombinant Protein

Specifications

Product Data
Species	Human
Protein Source	Human 293
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) Ala21-Phe375
Tag	C-6His
Buffer	Lyophilized from a 0.2 um filtered solution of 20mM PB, 150mM NaCl, pH 7.2
Note	Recombinant Human Surfactant protein D/SP-D (C-His) is produced by our Mammalian expression system and the target gene encoding GL signal- Ala21-Phe375-VD-6His is expressed with a 6His tag at the C-terminus.
Storage	Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-5 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Stability	12 months from date of despatch

Synonyms	Pulmonary Surfactant-Associated Protein D; PSP-D; SP-D; Collectin-7; Lung Surfactant Protein D; SFTPD; COLEC7; PSPD; SFTP4
Summary	Human Surfactant protein is a part of the collectin family of C-type lectins which are synthesized in respiratory epithelial cells in the lungs and contains two types of domains: C-type lectin and collage-like. This protein is a humoral molecule of the innate immune system and is involved in the development of acute and chronic inflammation of the lungs. Human Surfactant protein can be a therapeutic option for cystic fibrosis and a serum of this protein can be used as a disease activity marker for interstitial lung diseases.
